I'm looking for anyone with any information on a 4E vs 5E T1. We have a location that is having a LD T1 replaced and they were told they are going from a 4E to a 5E T1/Circuit. The circuit is connected to a H.323 gateway. What changes would be made for the change in circuit? Sorry I don't have a lot of information, but I'm just getting bits and pieces of information from the location. Thanks!
